[GRASS5] v.extract problems

[Roger Miller]

Folks,

I put together a new test case that was a bit cleaner than the one I was 
using previously.  Using the most recent version of v.extract I was able to 
extract a file with 5,000 categories from a file with 53,000 (plus or minus) 
categories without errors.  I also found no problem with the content of the 
file produced. 

Some of the problems I was finding earlier were apparently not inherent in 
the code, but were triggered by some characteristic of the data I was using.
Quite possibly someone in the future will trigger the problem again.
